Study summary

The evaluation of an accurate occurrence rate for AKI is of great importance for health policy, quality initiatives as well as for designing clinical trials.

The primary objective is to prospectively evaluate the incidence of AKI within 72 h after extended surgical procedures that require admission to an observation unit.

Read the detailed description

Acute kidney injury (AKI) is a severe clinical complication with increasing incidence and is associated with adverse short- and long-term outcomes resulting in a major health care burden worldwide. The introduction of consensus classification systems has enhanced the awareness for AKI. The evaluation of an accurate occurrence rate for AKI is of great importance for health policy, quality initiatives as well as for designing clinical trials. However, analyzing AKI from existing databases is often limited by missing data elements, especially the inclusion of the urine output criteria. Missing data and the use of different definitions before the consensus classification are the reasons for large variations in reported occurrences of surgical induced AKI.

The primary objective is to prospectively evaluate the incidence of AKI within 72 h after extended surgical procedures that require admission to an observation unit (e.g., Intensive Care Unit, Intermediate Care, Post Anesthesia Care Unit) using the latest consensus definition for AKI (Kidney Disease: Improving Global Outcomes criteria) and a standardized data collection instrument and to assess the dependence of AKI on preoperative and intraoperative factors.

Method: International prospective, observational, multi-center, cross-sectional cohort study

Eligible patients will be identified during preoperative assessment. All eligible patients will be approached to obtain written consent.

Study population

Adult patients undergoing extended surgical procedure and the need for postoperative observation

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • major elective or emergency surgery procedures with a duration of at least 2 h
  • admission to the intensive care unit, intermediate care unit after surgery

Exclusion criteria

Exclusion Criteria:

  • preexisting acute kidney injury
  • acute kidney injury within the last 3 months
  • end stage renal disease with dialysis dependency
  • kidney transplant
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2020 to primary completion in Feb 2022, 20 months.

Of 349 non-industry observational studies under Acute Kidney Injury, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 42. This study's 20 months is below that.

Counting every sponsor, half of 364 studies reached it within 24 months; a quarter within 12 and three quarters within 42.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 21, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
